WANTED: Critical Habitat for Monk Seal

KAHEA, along with the Center for Biological Diversity and the Ocean Conservancy, filed a formal petition yesterday, seeking to have beaches and surrounding waters on the main Hawaiian islands designated as critical habitat for Hawaiian monk seals under the Endangered Species Act.

Under the Endangered Species Act, critical habitat identifies geographic areas that contain features essential for the conservation of a threatened or endangered species and may require special management considerations.

Recent studies have shown that species with critical habitat are twice as likely to be recovering as species without it. Currently, the species has critical habitat designated only on the Northwestern Hawaiian Islands.

The Hawaiian monk seal is one of the most endangered marine mammals in the world. Since the 1950s its population has dropped to about 1,300 animals and is continuing to decline. Scientists estimate populations will likely drop below 1,000 seals within a few years.

Monk seals in the Northwestern Hawaiian Islands are dying of starvation, emaciated and weak, scientists have found. Pups have only about a one-in-five chance of surviving to adulthood. Other threats include drowning in abandoned fishing gear, shark predation, and disease.

Hawaiian monk seals are increasingly populating the main islands, where they are giving birth to healthy pups. For the past decade, the number of Hawaiian monk seal births has increased each year on the main islands, and the population of seals is growing steadily; the seals are in better condition than those in the Northwestern Hawaiian Islands. This indicates more food availability and a better chance of survival.

Global warming is also a threat to the survival of Hawaiian monk seals. Already, the conservation groups warn, important pupping beaches have been lost due to sea-level rise and erosion, and the northwestern islands will eventually disappear under predicted levels of sea-level rise since they are elevated only a few meters above sea level. The higher-elevation main islands are less vulnerable to sea-level rise.

Hawaiian monk seals are one of three species of monk seals. The Mediterranean monk seal is also critically endangered, while the Caribbean monk seal, which has not been seen in half a century, was declared extinct in June.

The Endangered Species Act requires that the government respond to this petition within 90 days.
